I thought someone with acres of experience might jump in to help a fellow out daisy but you did the right thing and they will come back. In fact, they may even be better for it.

Be patient and not too discouraged! Make sure you do not overwater since most transpiration has almost stopped. It is temporary...just use good housekeeping sense to keep sanitation levels and circulation high so you don't encourage root-rot and foliar fungus problems.
Remove loose foliage, water sparingly when necessary, perhaps use a fungicide as a precaution(especially for varieties that are highly susceptable).
Do not over fertilize, particularly if you have slow release incorporated in the potting media. If you are using a water soluble, continuous feeding program, reduce to 100-150ppm of 20-10-20*. I think you will be able to recover most varieties except for the most tender annuals such as Impatiens, Celosia, Lobelia, Torenia. Also, try to feed when the soil is slightly moist and not actually dry.(That may preclude the chance of burning the newly emerged tender foliage)

*Typically, I like to use the 20-10-20 formulations during the cool season and use tailored formulations for specific crops.
I hope this is is it progressing?
